Audi has said the number of cars delivered to customers worldwide in the first six months of the year rose 17.7% to more than 652,950 compared with the same period in 2010. From January through June, total sales in Europe rose by 13.5% to around 382,850 cars. The main drivers of this growth were the Audi A1 and the A8, the latter having been steadily increasing its market shares since its introduction at the start of last year. Sales of Audi’s large SUV, Q7, gained 23.5% over the same period last year, the German carmaker said.
